'5 Claims. ((51. 206-62).

This invention relates to packaging device for vehicle Windshields.

It is common today to have large vehicle Windshields at the front and'rear of passenger. vehicles and'these Windshields have a compoundcurvature in many cases which makes them difiicult to package and ship.The present invention contemplates a packaging device especially usefulfor rear window shields. These rear windows are formed of an extremelyhard glass which has a great deal of structural strength. It isimportant, however, that the edges of this glass be protected againstany chipping or abrasion.

The present packaging device contemplates a complete surrounding of theglass in an enclosure which, in itself, has no particular structuralstrength but which protects the glass from edge damage.

Other objects and features of the invention relating to the variousdetails and structure of the device will be apparent in the followingdescription and claims.

Drawings accompany the invention and the various views thereof may bebriefly described as:

Figure 1, a perspective view of the completed package.

Figure 2, a perspective view of a rear window glass ready for packaging.

Figure 3, a view of a one-piece packaging unit.

Figure 4, a sectional view on line 44 of Figure 2.

Figure 5, a sectional view on line 5-5 of Figure 1.

Figure 6, a sectional view on line 66 of Figure 1.

Figure 7, a view of a two-piece packaging shield.

Referring to the drawings:

In Figure 2, a glass is shown provided with small hard formed papercylindrical units 20, shown in cross section in Figure 4, taped onto theglass by strips 22. The packaging device shown in Figure 3 comprises asingle sheet of corrugated paper material or its equivalent which hasfold creases or scoring 24 formed in the ends to permit the ends to befolded around, as will later be described. In the top and bottom edgesare handle openings 26, at one side, and 27 at the other, the openings27 having flaps 28 which are not removed. Also at one longitudinal edgeare parallel slits which form tabs 30. At the other edge are openings 32to receive tabs 30. Centrally of the device a crease 34 is providedterminating in a notch 36 at each end, and slits 38 create tabs 40centrally of the device. Cut outs 42 below tabs 40 serve in co-operationwith tabs 40.

When the device is applied to the glass, as shown in Figure 1, thehandle of flaps 28 are passed through the handleholes 26 and stapled inplace, thus locking this edge of the package. At the bottom of the glassthe tabs 40 are folded through openings 42 to be snug with the bottomedge of the glass. Tabs 30, which are longer, are folded throughopenings 32 around the top edge of the glass, as shown in Figures 1 and5.

Thus, if the glass is varying in vertical height, the bottom tabs can befolded snug with the bottom edge of the glass, the tab 40 folding at itsbase. It is preferred itself fto. the particular size of the. glassbeing wrapped.

gagement with. the sidesof the package,.willtransmit the- 2 load to-alarge area.

The ends of the-package are completed by folding the twoendflaps 56-and. 58 in tight association with the ends of theglass on thenearestcrease 24 which adapts End. tab 56 is narrower than tab 58 due tocut-out..36 and a corner cut-out60. The end tabs may then. be stapled sothat the glass'will' not shift in the package. The end tabs 56 and 58may be folded together or alternately lapped over the ends of the glass.It is preferred that the wider tab 58 be stapled against itself. Thisalternate folding is shown in Figure 6.

In Figure 7, a slightly modified version of the construction is shown inwhich the front and back or top and bottom portions are split intoseparate units. The main panel 70 has a handle opening 72 and top andbottom fiaps 74 and 76. The ends of this panel are creased at 78. Thesupplementing panel has a top tab 82 with a handle opening and tab 84and a bottom tab 86 which registers with the inner cuts forming tabs 76.The narrower ends of panel 80 are also creased at 88.

In assembly, this device would operate in very much the same way as thedevice shown in Figure 3. The glass is sandwiched between the two panels70 and 80. The handle tab 84 is then passed through the opening 72 andstapled. First, the tabs 76 would be passed over the bottom edge of thepanel 80 to the full extent of their length, and then the longer tabs 74are passed over the top edge. of the panel 80 to such extent as willaccommodate the glass; then the device is taped as previously. The endsare closed and stapled as in the previous modification.

It will thus be seen that there is provided a complete enclosure for theedges of the tempered glass panel which can be shipped now withoutfurther packaging.v

The panel itself furnishes adequate strength for the unit and theprotective cover prevents edge damage to the panel. The panel ispositively spaced from the load bearing edges of the package so that thepanels, which are usually shipped on edge, will be cushioned againstdirect contact with a track floor or other conveyance.

What is claimed is as follows:

1. A protective shipping closure for frangible plates of varying lengthsand widths such as vehicle rear windows which comprises a frangibleplate of tempered glass, a panel overlying each face of said plate, eachpanel having projecting edges beyond the plate in all directions, meansengaging and clamping said portions of projecting edges together wherethey overlie each other, tab means and notches on said panelsregistering with each other wherein a tab on one panel is folded througha notch on, and over the outer face of, the other to effect registrationof said panels, and means holding said folded tab means in positionwherein said plate is confined always safely within the projecting edgesof said panels, said panels forming the complete protective closure incombination with said plate.

2. A closure as defined in claim 1 in which folded tabs and notches onone edge of said panels register transversely of said plate with foldedtabs and notches on another parallel edge of said panels, and said meansfor holding said tabs in position comprises strap-like materialencircling the panels at said registering notches.

3. A closure as defined in claim 1 in which one of said panels has endportions narrower than the other, both end portions being'folded oversaid plate and the wider end being fastened to itself outside saidnarrower end.

4. A protective shipping device for frangible plates of varying lengthsand widths such as vehicle rear windows which comprises a frangibleplate of tempered glass, a panel overlying each face of said plate, eachpanel being longer than the plate to be protected, one of said panelsbeing narrowed at the ends relative to the other whereby said ends areeach folded around the plate,

and means fastening each wider end to itself outside the narrower ends,central tabs extending from each side of one of said panels, andflanking tabs on the other of said panels positioned to register withedges of said central tabs, said flanking tabs being folded around andin contact with the outer face of said one panel adjacent thecentral'tabs to locate said panels relative to each other, and strapmeans to hold said flanking tabs in position around said one panel, saidpanels forming the of which project beyond all the boundaries of a plateto be protected, and means to interlock said panels against relativedisplacement to each other and to the plate which comprise intergagingtabs and notches in edge to edge contact with each other, said tabsbeing folded over the plate and the outer surface of the adjacent panelat the edges of the panel, and strap means to hold .said tabs in foldedposition, said panels forming the complete protective closure incombination with said plate.
